Abstract

The invention discloses biodegradable plastic taking egg shells as raw materials. The biodegradable plastic is characterized by being prepared from the following raw materials in parts by weight: 20-30 parts of egg shells, 10-15 parts of polyethylene, 10-15 parts of glutinous rice flour, 5-10 parts of bean curd residue powder, 4-8 parts of pineapple leaves, 3-5 parts of xanthan gum, 2-4 parts of sodium caseinate, 0.1-0.2 part of calcium propionate, 1-2 parts of sodium polyacrylate, 4-6 parts of castor oil, 1-2 parts of a silane coupling agent KH-550 and 10-15 parts of a compound auxiliary agent. The biodegradable plastic disclosed by the invention is high in degradation rate and high in degradation speed, also has good flexibility and strength which meets the use requirements, is simple in production process, ensures that white pollution can be effectively reduced, and has relatively high environmental and economic benefits.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a biodegradable plastic made from eggshells and a preparation method thereof. Background technique [0002] With the development of industry, plastics have been widely used in life, but it brings a lot of solid waste, especially disposable plastic products such as plastic packaging bags, shopping bags, plastic lunch boxes and mulch, etc. Products are disposed of as solid waste after use. Due to the characteristics of waste plastics that are difficult to degrade naturally and the harmful treatment methods, the plastic waste generated remains in water bodies and land, forming "white pollution", deteriorating the environment, and threatening the survival of human beings, becoming a public hazard in the world. [0003] In order to solve the pollution problem caused by plastic waste, degradable plastics have become a hot spot in research and development. Biodegradable plastics are ...
